For 3D SSI problem in Opensees giving eqdof or rigidlink b/n structure base & proximity stdbrick element node didnt work

I defined my structure with a model builder of -ndm 3 -ndf 6 and my soil as -ndm 3 -ndf 3 with a stdbrick element. I connected the base of the structure with the brick elements with eqdof in dof1 and dof2. my analysis failed :shock: even for gravity load. what kind of constraints did you use to conn...

can't use non-numeric floating-point value as operand of "/"

I'm trying to do an analysis considering soil. I used Gid+Opensees to visualize my model and then get the tcl code. I get the following error. #================================================== can't use non-numeric floating-point value as operand of "/" while executing "expr 6.283185/sqrt($lam)" (...

Re: BandSPDLinLapackSolver

Is there any way I can model Shearwalls other than THUShell elements? Can I model elastic shear wall elements or by using fiber elements? I changed the column and beams to elastic elements but still, I got convergence errors when doing Pushover analysis or couldn't do Gravity analysis.

ForceBeamColumn3d::update() -- could not invert flexibility

I modeled a 4 story 2 way assymetric reinfoced concrete model in Opensees and when analyzing for gravity load I get the above error. I modeled the shearwall using multi-layer shell element THUShell. I was using "forceBeamColumn" element for the beam and column elements with Lobatto integrator. I als...

BandSPDLinLapackSolver

Hi I'm having a problem when I run a 3-D model for gravity load. My model is a two way asymmetric 4 story structure with Shear wall modeled with ShellMITC4. It appears to give this warning when running for gravity analysis. Start of gravity analysis generation WARNING BandSPDLinLapackSolver::solve()...
